BIG ROCK POINT SENI-ANNUAL RADIdACTIVE EFFLUENT RELEASE REPORT July 1.1992 to December 31. 1992 This report provides information relating to radioactive effluent releases and solid radioactive waste processing at the Big Rock Point during the period of l

July 1 through December 31, 1992. The report format is detailed in Plant l

Technical Specification 6.9.2.2.

Big Rock Point was offline during the following times: 1) August 13, 1992 thru August 17, 1992 for turbine work; I

2) August 20, 1992 thru August 25, 1992 due to turbine..ork; 3) August 30, l

1992 thru September 3,1992 to repair a leak on a heat exchanger on a Reactor Coolant Pump; 4) October 5,1992 thru October 8,.1992 to replace a Reactor Coolant Pump Seal; 5) October 30, 1992 thru November 2, 1992 due to substation l

problems; 6) December 7,1992 thru December 10, 1992 for steam leak repairs and a condensor tube plug.

Supplemental Information A.

Batch Releases l

Information relating to continuous and batch releases of gaseous and liquid effluents.is provided in Table HP 10.3-1.

B.

Abnormal Releases None C.

Lower Limits of Detection (LLD's) for gaseous and liquid effluents is provided in Attachment 1.

2.

Gaseous Effluents Table HP 10.3-2 lists and summarizes all gaseous radioactive effluents released during the reporting period. The unidentified beta was 0.00E+00% of the total release.

3.

Liouid Effluents Table HP 10.3-3 lists and summarizes all liquid radioactive effluents released during the reporting period. The unidentified beta was 2.50E+00% of the total releases.

4.

Solid Waste There wei-e no solid waste radwaste shipments from July 1 to December 31, 1992.

2 Potential doses to individuals and populations were calculated using GASPAR and LADTAP computer program codes. The third and fourth quarter values.for curies released were input for each nuclide and sumarized i

j as follows:

i j

A.

The offsite air dose at the site boundary (0.57 mi E) due to noble i

gases were 8.95E-04 millirad beta and 1.28E-03 millirad gamma for the third quarter; and 1.43E-03 millirad beta and 2.09E-03 l

millirad gamma for the fourth quarter. Th? maximum noble gas offsite air dose to the nearest residence (1.4 mi E) occurred j

during the fourth quarter, being 6.99E-03.millirads beta and 1.20E-02 millirads gamma.

l

\\

i j

B.

The most restrictive organ dose to an individual in an unrestricted area (based on identified critical receptors) from i

gar 3ous effluent releases (tritium, particulate and iodine) was j

the infant thyroid for the third and fourth quarters.

Doses were 1

9.77E-03 and 3.35E-03 millir-en, respectively.

(

i r

C.

Integrated total body does to the general population and average i

j doses to individuals within the population from gaseous effluent j

release pathways to a distance of 50 miles from the site boundary were: 5.04E-03 Person-Rem and 3.28E-05 millirem for the third quarter; and 8.27E-03 Person-Rem and 5.38E-05 millirem for the fourth quarter.

l D.

The maximum total body dose to an individual in unrestricted

' water-related exposure pathways was 1.28E-03 (adult) and 1.01E-03 j

(teen) millirems for the third and fourth quarters, respectively.

l

{

The maximum organ doses were 2.25E-03 millirem (teenager liver) j for the third quarter and 2.81E-03 millires (adult bone) for the fourth quarter.

E.

Integrated total body doses to the general population and average j

doses to individuals within the pcpulation from liquid effluent release pathways to a distance of 50 miles from the site boundary were: 7.97E-04 Person-Rem and 5.18E-06 millires, respectively, for the third quarter; and 8.04E-04 Person-Rem and 5.22E-06 millirem, respectively, for the fourth quarter.

6.

Process Control Proaram (PCP)

There were no changes to the PCP during this reporting period.

7.

There were no changes to the ODCM during this reporting period.
